The subject procurement will upgrade the existing macroscopic 4-stage traffic model for hourly and daily traffic. The hourly traffic model is the basis for the operation of the dynamic traffic simulation model, as the matrices for each hour of the day, the number of vehicles on the section and the traffic network from the macroscopic traffic model are the input data for the dynamic simulation model.

The results of the macroscopic traffic model are the basis for:

  • forecasting traffic loads for new measures on the transport network;
  • the production of statistical traffic analyses;
  • data input into the National Congestion Register (NCR) and from the NCR into the macroscopic traffic model or PTV Visum;
